Mixed reality interactions

ABSTRACT

Embodiments that relate to interacting with a physical object in a mixed reality environment via a head-mounted display are disclosed. In one embodiment a mixed reality interaction program identifies an object based on an image from captured by the display. An interaction context for the object is determined based on an aspect of the mixed reality environment. A profile for the physical object is queried to determine interaction modes for the object. A selected interaction mode is programmatically selected based on the interaction context. A user input directed at the object is received via the display and interpreted to correspond to a virtual action based on the selected interaction mode. The virtual action is executed with respect to a virtual object associated with the physical object to modify an appearance of the virtual object. The modified virtual object is then displayed via the display.

BACKGROUND

Searching for and retrieving relevant information using computingdevices is a common task. Typical computing devices that are used tofind and display information may include smartphones, tablets, notebookcomputers, and the like. Such computing devices, however, are typicallylimited to connecting a user to relevant information via dedicatedgraphical user interfaces and corresponding display elements, such asweb search portals, hyperlinks, etc. These well-known interfaces anddisplay elements generated by a corresponding computing device are tiedto the device, and generally embody little or no context linking them tothe user or the user's environment. Further, typical computing devicesare fairly limited in their capacity to understand an environment inwhich they are used and/or to link user activity within the environmentto information relevant to the user.

DETAILED DESCRIPTION

FIG. 1 shows a schematic view of one embodiment of a mixed realityinteraction system 10. The mixed reality interaction system 10 includesa mixed reality interaction program 14 that may be stored in massstorage 18 of a computing device 22. The mixed reality interactionprogram 14 may be loaded into memory 28 and executed by a processor 30of the computing device 22 to perform one or more of the methods andprocesses described in more detail below.

The mixed reality interaction system 10 includes a mixed reality displayprogram 32 that may generate a virtual environment 34 for display via adisplay device, such as the head-mounted display (HMD) device 36, tocreate a mixed reality environment 38. As described in more detailbelow, the virtual environment 34 may include one or more virtualobjects, such as virtual object1 40, virtual object2 42, and geo-locatedtarget virtual object 52. Such virtual objects may include one or morevirtual images, such as three-dimensional holographic objects and othervirtual objects, as well as two-dimensional virtual images, that aregenerated and displayed by HMD device 36.

The computing device 22 may take the form of a desktop computing device,a mobile computing device such as a smart phone, laptop, notebook ortablet computer, network computer, home entertainment computer,interactive television, gaming system, or other suitable type ofcomputing device. Additional details regarding the components andcomputing aspects of the computing device 22 are described in moredetail below with reference to FIG. 5.

The computing device 22 may be operatively connected with the HMD device36 using a wired connection, or may employ a wireless connection viaWiFi, Bluetooth, or any other suitable wireless communication protocol.For example, the computing device 22 may be communicatively coupled to anetwork 16. The network 16 may take the form of a local area network(LAN), wide area network (WAN), wired network, wireless network,personal area network, or a combination thereof, and may include theInternet.

As described in more detail below, the computing device 22 maycommunicate with one or more other computing devices, such as server 20,via network 16. Additionally, the example illustrated in FIG. 1 showsthe computing device 22 as a separate component from the HMD device 36.It will be appreciated that in other examples the computing device 22may be integrated into the HMD device 36.

With reference now also to FIG. 2, one example of an HMD device 200 inthe form of a pair of wearable glasses with a transparent display 44 isprovided. It will be appreciated that in other examples, the HMD device200 may take other suitable forms in which a transparent,semi-transparent or non-transparent display is supported in front of aviewer's eye or eyes. It will also be appreciated that the HMD device 36shown in FIG. 1 may take the form of the HMD device 200, as described inmore detail below, or any other suitable HMD device. Additionally, manyother types and configurations of display devices having various formfactors may also be used within the scope of the present disclosure.Such display devices may include hand-held smart phones, tabletcomputers, and other suitable display devices.

With reference to FIGS. 1 and 2, the HMD device 36 includes a displaysystem 48 and transparent display 44 that enables images such asholographic objects to be delivered to the eyes of a user 46. Thetransparent display 44 may be configured to visually augment anappearance of a physical environment 50 to a user 46 viewing thephysical environment through the transparent display. For example, theappearance of the physical environment 50 may be augmented by graphicalcontent (e.g., one or more pixels each having a respective color andbrightness) that is presented via the transparent display 44 to create amixed reality environment.

The transparent display 44 may also be configured to enable a user toview a physical, real-world object, such as physical object1 54 and/orphysical object2 58, in the physical environment 50 through one or morepartially transparent pixels that are displaying a virtual objectrepresentation. As shown in FIG. 2, in one example the transparentdisplay 44 may include image-producing elements located within lenses204 (such as, for example, a see-through Organic Light-Emitting Diode(OLED) display). As another example, the transparent display 44 mayinclude a light modulator on an edge of the lenses 204. In this examplethe lenses 204 may serve as a light guide for delivering light from thelight modulator to the eyes of a user. Such a light guide may enable auser to perceive a 3D holographic image located within the physicalenvironment 50 that the user is viewing, while also allowing the user toview physical objects in the physical environment, thus creating a mixedreality environment.

The HMD device 36 may also include various sensors and related systems.For example, the HMD device 36 may include an eye-tracking system 62that utilizes at least one inward facing sensor 216. The inward facingsensor 216 may be an image sensor that is configured to acquire imagedata in the form of eye-tracking data 66 from a user's eyes. Providedthe user has consented to the acquisition and use of this information,the eye-tracking system 62 may use this information to track a positionand/or movement of the user's eyes.

In one example, the eye-tracking system 62 includes a gaze detectionsubsystem configured to detect a direction of gaze of each eye of auser. The gaze detection subsystem may be configured to determine gazedirections of each of a user's eyes in any suitable manner. For example,the gaze detection subsystem may comprise one or more light sources,such as infrared light sources, configured to cause a glint of light toreflect from the cornea of each eye of a user. One or more image sensorsmay then be configured to capture an image of the user's eyes.

Images of the glints and of the pupils as determined from image datagathered from the image sensors may be used to determine an optical axisof each eye. Using this information, the eye-tracking system 62 may thendetermine a direction and/or at what physical object or virtual objectthe user is gazing. Such eye-tracking data 66 may then be provided tothe computing device 22. It will be understood that the gaze detectionsubsystem may have any suitable number and arrangement of light sourcesand image sensors.

The HMD device 36 may also include sensor systems that receive physicalenvironment data 60 from the physical environment 50. For example, theHMD device 36 may include an optical sensor system 68 that utilizes atleast one outward facing sensor 212, such as an optical sensor, tocapture image data 74. Outward facing sensor 212 may detect movementswithin its field of view, such as gesture-based inputs or othermovements performed by a user 46 or by a person or physical objectwithin the field of view. Outward facing sensor 212 may also capturetwo-dimensional image information and depth information from physicalenvironment 50 and physical objects within the environment. For example,outward facing sensor 212 may include a depth camera, a visible lightcamera, an infrared light camera, and/or a position tracking camera.

The HMD device 36 may include depth sensing via one or more depthcameras. In one example, each depth camera may include left and rightcameras of a stereoscopic vision system. Time-resolved images from oneor more of these depth cameras may be registered to each other and/or toimages from another optical sensor such as a visible spectrum camera,and may be combined to yield depth-resolved video.

In other examples a structured light depth camera may be configured toproject a structured infrared illumination, and to image theillumination reflected from a scene onto which the illumination isprojected. A depth map of the scene may be constructed based on spacingsbetween adjacent features in the various regions of an imaged scene. Instill other examples, a depth camera may take the form of atime-of-flight depth camera configured to project a pulsed infraredillumination onto a scene and detect the illumination reflected from thescene. It will be appreciated that any other suitable depth camera maybe used within the scope of the present disclosure.

Outward facing sensor 212 may capture images of the physical environment50 in which a user 46 is situated. In one example, the mixed realitydisplay program 32 may include a 3D modeling system that uses such inputto generate a virtual environment 34 that models the physicalenvironment 50 surrounding the user 46.

The HMD device 36 may also include a position sensor system 72 thatutilizes one or more motion sensors 220 to capture position data 76, andthereby enable motion detection, position tracking and/or orientationsensing of the HMD device. For example, the position sensor system 72may be utilized to determine a direction, velocity and acceleration of auser's head. The position sensor system 72 may also be utilized todetermine a head pose orientation of a user's head. In one example,position sensor system 72 may comprise an inertial measurement unitconfigured as a six-axis or six-degree of freedom position sensorsystem. This example position sensor system may, for example, includethree accelerometers and three gyroscopes to indicate or measure achange in location of the HMD device 36 within three-dimensional spacealong three orthogonal axes (e.g., x, y, z), and a change in anorientation of the HMD device about the three orthogonal axes (e.g.,roll, pitch, yaw).

Position sensor system 72 may also support other suitable positioningtechniques, such as GPS or other global navigation systems. Further,while specific examples of position sensor systems have been described,it will be appreciated that other suitable position sensor systems maybe used. In some examples, motion sensors 220 may also be employed asuser input devices, such that a user may interact with the HMD device 36via gestures of the neck and head, or even of the body. The HMD device36 may also include a microphone system 80 that includes one or moremicrophones 224 that capture audio data 82. In other examples, audio maybe presented to the user via one or more speakers 228 on the HMD device36.

The HMD device 36 may also include a processor 230 having a logicsubsystem and a storage subsystem, as discussed in more detail belowwith respect to FIG. 5, that are in communication with the varioussensors and systems of the HMD device. In one example, the storagesubsystem may include instructions that are executable by the logicsubsystem to receive signal inputs from the sensors and forward suchinputs to computing device 22 (in unprocessed or processed form), and topresent images to a user via the transparent display 44.

It will be appreciated that the HMD device 36 and related sensors andother components described above and illustrated in FIGS. 1 and 2 areprovided by way of example. These examples are not intended to belimiting in any manner, as any other suitable sensors, components,and/or combination of sensors and components may be utilized. Thereforeit is to be understood that the HMD device 36 may include additionaland/or alternative sensors, cameras, microphones, input devices, outputdevices, etc. without departing from the scope of this disclosure.Further, the physical configuration of the HMD device 36 and its varioussensors and subcomponents may take a variety of different forms withoutdeparting from the scope of this disclosure.

With reference now to FIG. 3, descriptions of example use cases andembodiments of the mixed reality interaction system 10 will now beprovided. FIG. 3 provides a schematic illustration of a user 304 locatedin a physical environment 50 that comprises an office 308, with the userexperiencing a mixed reality environment 38 via an HMD device 36 in theform of HMD device 200. As discussed in more detail below, in FIG. 3 themixed reality environment 38 may comprise the office 308 and one or morephysical objects, as well as a virtual environment including one or morevirtual objects.

In the example illustrated in FIG. 3, the user 304 sits at a desk 312that includes a framed photograph 316 of the user's spouse and akeyboard 320. The optical sensor system 68 of the HMD device 200 maycapture image data 74 from the office 308, including image datarepresenting the photograph 316 and other physical objects in theoffice, such as table 324, book 328 on the table, basketball 332,bookcase 334 and coat rack 338. Image data 74 of one or more of thesephysical objects may be provided by the HMD device 200 to the mixedreality interaction program 14.

Using this image data 74, the mixed reality interaction program 14 mayidentify one or more of these physical objects. For example, the mixedreality interaction program 14 may identify the photograph 316 and theface of the user's spouse in the photograph by comparing image data 74of the face to stored face image data and corresponding identitieslocated on server 20. In this example, the mixed reality interactionprogram 14 may include a face detection subsystem that detects faceimages in the image data 74. To detect a face image in the image data74, the face detection subsystem may use any suitable face detectiontechnologies and/or algorithms including local binary patterns (LBP),principal component analysis (PCA), independent component analysis(ICA), evolutionary pursuit (EP), Elastic Bunch Graph Matching (EBGM),or other suitable algorithm or combination of algorithms.

The face detection program may access object profile data 92 on server20 to match image data 74 including the face in photograph 316 with oneor more images and related user profile information corresponding touser's spouse. It will be appreciated that the face detection programmay use any suitable facial recognition techniques to match image data74 with stored images of the user's spouse.

The mixed reality interaction program 14 also determines an interactioncontext 84 for the framed photograph 316 based on one or more aspects ofthe mixed reality environment 38. With reference again to FIG. 1, suchaspects of the mixed reality environment 38 may include one or more datafeeds 86 originating from the mixed reality environment 38 or externallyto the mixed reality environment. Data feeds 86 may include temporaldata, such as time of day, day of week, month, season, etc., socialnetworking data, such as postings, status updates, etc. related to user304, location data, weather data, etc.

In some examples and with reference to FIG. 3, such aspects of the mixedreality environment 38 may also include information more directly linkedto the office 308. Such information may include the presence of one ormore other persons in the office 308, the identities of such persons, anambient light level, an ambient noise level, etc. In other examples,such aspects of the mixed reality environment 38 may also includeinformation related to the user 304, such as user biometric parametersincluding, for example, heart rate, pupillary response, hemoglobinsaturation, skin conductivity, respiration, perspiration, and brainwaveactivity.

In one example, the mixed reality interaction program determines that acurrent time of day is 10:30 am in the mixed reality environment 38. Itwill be appreciated that the time of day may be determined, for example,by an internal clock within computing device 22 or may be received froman external source via data feeds 86. Accordingly, in the presentexample the mixed reality interaction program 14 uses the current timeof day of 10:30 am to determine a Business-Time interaction context forthe photograph 316.

Having identified the face of the user's spouse in the photograph 316,the mixed reality interaction program 14 may then query a stored profileof the user's spouse in object profile data 92 to determine a pluralityof interaction modes 88 that are available for the photograph 316. Asdescribed in more detail below, each of the plurality of interactionmodes 88 may correspond to a different virtual action 90 that may betaken with respect to the photograph 316. In the present example, theavailable interaction modes 88 may include a Family Calendar interactionmode and a Family Reunion Planning interaction mode. In other examples,the mixed reality interaction program 14 may create a new profile forthe photograph 316 that associates one or more interaction modes withthe photograph. For example, the mixed reality interaction program 14may enable the user 304 to create a new profile for the photograph 316when, for example, a relationship status has changed.

Next, based on the determined interaction context, the mixed realityinteraction program 14 may programmatically select a selectedinteraction mode. In the present example, with the determinedinteraction context being Business-Time, the mixed reality interactionprogram 14 programmatically selects a Family Calendar interaction mode.In one example, the Business-Time interaction context may be defined asa time of day falling between 8:00 am and 6:00 pm. The mixed realityinteraction program 14 may be configured to pair the Business-Timeinteraction context with the Family Calendar interaction mode withrespect to the photograph 316.

Another interaction context, a Personal-Time interaction context, may bedefined as a time of day falling between 6:01 pm and 7:59 am. The mixedreality interaction program 14 may be configured to pair thePersonal-Time interaction context with a Family Reunion Planninginteraction mode with respect to the photograph 316.

In the present example, the mixed reality interaction program 14 mayreceive a user input from user 304 that is directed at the photograph316. For example, the mixed reality interaction program 14 may receiveeye-tracking data 66 from the HMD device 200 indicating that the user304 is gazing at the photograph 316, as indicated by gaze line 336. Inother examples, the user input may take one or more other formsincluding, for example, position data 76 and image data 74. The positiondata 76 may include head pose data indicating that the user 304 isfacing the photograph 316. The image data 74 may include image datashowing the user 304 pointing or gesturing at the photograph 316. Itwill be appreciated that other forms of user input may similarly beutilized.

The mixed reality interaction program 14 may then interpret the user 304gazing at the photograph 316 to correspond to a virtual action 90. Thevirtual action 90 may be based on the selected interaction mode, in thisexample the Family Calendar interaction mode. The virtual action 90 maycomprise presenting to the user 304 a virtual object in the form of theuser's family calendar stored in a calendar application. It will beappreciated that the user's family calendar is associated with thephotograph 316 of the user's spouse.

The mixed reality interaction program 14 may then execute the virtualaction 90 with respect to a virtual instantiation of the user's familycalendar to modify an appearance of the calendar. For example, tocomfortably display the user's family calendar to the user 304, themixed reality interaction program 14 may control the mixed realitydisplay program 32 to scale the virtual instantiation of the calendar toa predetermined size. The mixed reality interaction program 14 may thendisplay the virtual instantiation of the user's family calendar with themodified appearance, as indicated at 340, via the mixed reality displayprogram 32 and HMD device 200.

In other examples, the mixed reality interaction program 14 may enablethe user 304 to create and add new virtual actions 90 that areassociated with the photograph 316. For example, the user 304 may createa virtual action that includes highlighting family members' birthdays onthe family calendar. Thereafter, when the user 304 gazes at thephotograph 316, the mixed reality interaction program 14 will highlightfamily members' birthdays on the displayed family calendar.

In one example, the mixed reality interaction program 14 may geo-locatethe family calendar 340 in physical proximity to the photograph 316. Asshown in FIG. 3, in the present example the calendar 340 may bedisplayed just above the photograph 316 such that when the user 304gazes at the photograph, the calendar is presented in an easily viewablelocation just above the photograph. Being geo-located to the photograph316, the calendar 340 may remain “tethered” to the photograph and maytrack the location of the photograph in the office 308. Advantageously,if the photograph 316 is moved to another location in the office 308,the user 304 may still easily recall and view the calendar 340 by gazingat the photograph 316.

In another example, the user 304 may use his right hand 344 to point atthe basketball 332 near wall 348. The mixed reality interaction program14 may identify the basketball, determine an interaction context for thebasketball, query a stored profile for the basketball, andprogrammatically select a selected interaction mode based on theinteraction context in a manner similar to that described above for thephotograph 316. A camera in the HMD device 200 may capture image data 74showing the user's right hand 344 pointing at the basketball 332. Themixed reality interaction program 14 may interpret this user input tocorrespond to displaying a website of the user's favorite basketballteam.

The mixed reality interaction program 14 may then modify image data ofthe website to, for example, enhance the contrast of the displayedwebsite when displayed above the basketball and in front of the wall348. The mixed reality interaction program 14 may then display aholographic version of the modified website 352 above the basketball332. The website 352 may also be geo-located to the basketball 332 suchthat it follows the basketball to different locations in the office 308,as indicated by basketball 332′ and website 352′ located near the leftrear corner of the office.

In some examples, the mixed reality interaction program 14 may be unableto determine the identity of a physical object, or may determine anincomplete identity of the object. For example, the mixed realityinteraction program 14 may not recognize a visitor 342 who enters theoffice 308. The mixed reality interaction program 14 may also determinethat the user 304 currently has a meeting in the office 308 scheduled inthe user's calendar with a John Doe. Based on this meeting, the mixedreality interaction program 14 may then query the user 304, “Is thisJohn Doe?” via text displayed on the HMD device 200. The user 304 mayprovide a confirmation of the identity of the visitor 342 by, forexample, nodding, speaking “Yes”, or by any other suitable input.

In another example, where the user 304 does not confirm that the visitor342 is John Doe, the mixed reality interaction program 14 may presentanother query to the user requesting the identity of the visitor. Whenthe user 304 answers and provides an identity of the visitor, such as,“This is John Smith,” the program may then associate the identity JohnSmith with the visitor. It will also be appreciated that such identityconfirmation processes may be used with any other physical objects.

In another example, the mixed reality interaction program 14 maydetermine a change in the interaction context 84 and may correspondinglychange the interaction mode 86. For example, the user 304 may be workingin the office 308 late one night. At 7:01 pm the mixed realityinteraction program 14 determines that the interaction context changesfrom Business-Time to Personal-Time. Accordingly, the mixed realityinteraction program 14 may programmatically select the Family ReunionPlanning interaction mode with respect to the photograph 316.

The mixed reality interaction program 14 may then interpret the user 304gazing at the photograph 316 to correspond to a virtual action 90 thatis based on the Family Reunion Planning interaction mode. In thisexample, the virtual action 90 may comprise highlighting the dates 364of the user's family reunion gathering in the user's family calendar340. The mixed reality interaction program 14 may then execute thevirtual action with respect to the calendar 340 to modify an appearanceof the calendar. For example, the mixed reality interaction program 14may control the mixed reality display program 32 to highlight inflashing color the dates 364 of the family reunion gathering in thecalendar 340. The mixed reality interaction program 14 may then renderand display the calendar 340 with the highlighted dates 364 via themixed reality display program 32.

In another example, after determining a change in the interactioncontext 84 to the Family Reunion Planning interaction mode, the mixedreality interaction program 14 may execute a different virtual action 90with respect to a different virtual object that is associated with thephotograph 316. For example, the mixed reality interaction program 14may display a virtual family reunion To-Do List 360 via the mixedreality display program 32 and HMD device 200 to the user 304. As withthe family calendar 340, the mixed reality interaction program 14 maycontrol the mixed reality display program 32 to scale a virtualinstantiation of the family reunion To-Do List 360 to a predeterminedsize. The mixed reality interaction program 14 may then display theTo-Do List 360, via the mixed reality display program 32 with themodified appearance.

In another example, the user 304 may desire to manually switch betweenthe Family Calendar interaction mode and the Family Reunion Planninginteraction mode. The user may request that the current Family Calendarinteraction mode be modified by, for example, speaking “Switch to FamilyReunion Planning.” The mixed reality interaction program 14 interpretsthis user input as a request to modify the interaction mode, and changesthe interaction mode accordingly. The user may then point at thephotograph 316, which is captured as image data 74 via the HMD device200. The mixed reality interaction program 14 interprets this user inputas corresponding to a virtual action 90 based on the Family ReunionPlanning interaction mode, such as displaying the virtual family reunionTo-Do List 360. The mixed reality interaction program 14 may thenexecute the virtual action and display the family reunion To-Do List 360with a modified appearance as described above.

In another example, the mixed reality interaction program 14 may displaya target virtual object that may function to enable user interactionwith another virtual object in a manner similar to that described above.For example, the mixed reality interaction program 14 may display ageo-located target virtual object 52 in the form of a holographic wizard370 located on table 324 in the mixed reality environment 38. The mixedreality interaction program 14 may then determine a Business-Timeinteraction context for the wizard 370 based on one or more aspects ofthe mixed reality environment 38.

The mixed reality interaction program may query a stored profile of theholographic wizard 370 in the object profile data 92 to determine aplurality of interaction modes 88 that are available for the wizard. Inthe present example, the available interaction modes 88 may include aStock Market interaction mode and a Movie Listings interaction mode.Next, based on the determined interaction context, the mixed realityinteraction program 14 may programmatically select a selectedinteraction mode. In the present example, with the determinedinteraction context being Business-Time, the mixed reality interactionprogram 14 programmatically selects the Stock Market interaction mode.

In the present example, the mixed reality interaction program 14 mayreceive a user input from user 304 that is directed at the holographicwizard 370, such as position data 76 including head pose data indicatingthat the user's face is oriented toward the wizard 370. The mixedreality interaction program 14 may then interpret the user 304 facingthe wizard 370 to correspond to a virtual action 90 that is based on theselected interaction mode, in this example the Stock Market interactionmode, and is associated with the wizard 370. The virtual action 90 maycomprise presenting a stock market summary 374 via the mixed realitydisplay program 32 and HMD device 200 to the user 304.

The mixed reality interaction program 14 may then execute the virtualaction 90 with respect to the stock market summary to, for example,highlight quotes of stocks owned by the user 304, such as the XYZ stockquote 376. The mixed reality interaction program 14 may control themixed reality display program 32 to highlight the XYZ stock quote 376.The mixed reality interaction program 14 may then display the stockmarket summary 374 via the mixed reality display program 32.

In another example, the mixed reality interaction program 14 may alsouse a user input to create an association between a physical object anda selected interaction mode. With continued reference to FIG. 3, in oneexample the user 304 may desire to associate the basketball 332 with theAnytown Ants website 352. The user 304 may pick up the basketball 332and rotate the basketball in the user's hands.

Using image data 74, the mixed reality interaction program 14 mayrecognize the user's rotation of the basketball 332 as a trigger todisplay to the user 304 the available interaction modes 88 for thebasketball. Such interaction modes 88 may include, for example,displaying the Anytown Ants website, displaying a scoreboard of currentbasketball games, and displaying a calendar showing upcoming games inthe user's basketball league. The user 304 may then select the AnytownAnts website interaction mode to associate with the basketball 332 viauser input received by the HMD device 200. Accordingly, the mixedreality interaction program 14 may then be configured to associate thebasketball 332 with the Anytown Ants website interaction mode.Subsequently, the mixed reality interaction program 14 may execute avirtual action with respect to the Anytown Ants website that isassociated with the basketball 332 when user input directed at thebasketball 332 is received, as described above.

It will be appreciated that the present system may enhance a user'sability to associate particular information sources, portals, etc. withobjects in the mixed reality environment 38, whether physical objects orvirtual objects. For example, by linking the holographic wizard 370 witha displayed stock market summary, the user may more easily remember touse the wizard to see the stock market summary during business hours.The user may, for example, memorize the phrase, “I'm a Wizard of thestock market” to provide an easily-remembered cognitive link between theholographic wizard 370 in the user's office 308 and the stock marketsummary.

In another example, the mixed reality interaction program 14 maygenerate audio feedback that is perceived by the user 304 as originatingfrom a virtual object or physical object in the office 308. The mixedreality interaction program 14 may utilize a three-dimensional audiopositioning technique, such as a head-related transfer function, togenerate such audio feedback via speakers 228 of the HMD 200. In oneexample, the mixed reality interaction program 14 may generate audiocomprising a broadcast of an Anytown Ants basketball game that isperceived by the user 304 as originating from the virtual website 352 orthe basketball 332.

In another example, the mixed reality interaction program 14 may beconfigured to take a virtual action with respect to an object that isplaced on the table 324. With reference to FIG. 3, the mixed realityinteraction program 14 may recognize that book 328 is resting on thetable 324. Accordingly, based on the book 328 resting on the table 324,the mixed reality interaction program 14 may programmatically post astatus update to the user's social network that notes that the user 304is currently reading book 328.

In another example, the mixed reality interaction program 14 may beconfigured to take a virtual action when a state of an object changes.For example, the mixed reality interaction program 14 may identify thatthe user 304 has begun drinking his regular cup of morning coffee at6:30 am. The program may monitor the amount of coffee remaining in theuser's cup. If a predetermined amount of coffee is remaining in the cupand the user attempts to check email, the program may prevent ordissuade the user from checking email. For example, upon detecting anattempt to check email, the program may display a message to the userasking, “Wouldn't you like to finish your relaxing cup of coffee first?”

In another example, a document related to a work project managed by theuser 304 may be linked to the user, such as in the object profile data92. A fellow team member of the work project may also wear an HMD device200 that is communicatively coupled to a mixed reality interactionprogram 14. When the fellow team member sees the user 304, the teammember's mixed reality interaction program 14 recognizes the user 304and displays the document related to the work project via the teammembers' HMD device 200.

In another example, a team member may virtually deliver a document tothe user 304 via leaving a physical or virtual object on the user's desk312. For example, a team member of the user 304 may associate thedocument with a cardboard cutout of the letter “D.” The team member mayleave the cutout D on the user's desk 312 while the user 304 is away.Upon returning to the office 308, the user's HMD device 200 mayrecognize the cutout D. The HMD device 200 may indicate to the user 304that the cutout D is actively linked to virtual information by, forexample, animating the cutout D, such as by causing the cutout D to glowwhen viewed. The user 304 may request to view the linked virtualinformation, and the HMD device 200 may then access the document linkedto the cutout D, and may display the document for the user 304.

In another example, the user 304 may provide a user input that appliesto multiple virtual objects associated with multiple physical objects.For example and with reference to FIG. 3, the user 304 may desire to dimall of the virtual objects displayed in the office 308. The user 304 mayextend his right hand 344 outwardly and lower his hand toward the desk312. The mixed reality interaction system 10 may recognize this gesture,and may correspondingly dim all of the virtual objects displayed via HMD200.

In another example, when the user 304 gazes at the basketball 332, themixed reality interaction program 14 may interpret the user's gaze tocorrespond with displaying over the basketball a virtual volume controlknob. The volume control knob may be virtually rotated by the user 304to adjust the volume of the broadcast of the Anytown Ants basketballgame to which the user is listening. The current volume may also bedisplayed as a digital volume indicator 380. In another example, theuser 304 may pick up and physically rotate the basketball 332 tocorrespondingly adjust the volume of the broadcast via the virtualvolume control knob.

In another example, while the user 304 is away from the office 308, thevisitor 342 may pick up and rotate the basketball 332 to lower thevolume of the basketball game broadcast that is being delivered byspeakers in the room 308. When the user 304 returns to the office 308,the mixed reality interaction program 14 may identify the neworientation of the basketball 332 and correspondingly lower the volumeof the broadcast being delivered to the user via HMD 200. The programmay also correspondingly modify the volume indicator 380.
